问题 How do I insert a BIT value in MySQL using a PDO Prepared Statement? Below is what I tried and my results. <?php function testIt($value) { $sql='INSERT INTO test(id,data) VALUES(?,?)'; $stmt=db::db()->prepare($sql); $stmt->execute(array(0,$value)); $id=db::db()->lastInsertId(); $sql='SELECT * FROM test WHERE id='.$id; $stmt=db::db()->query($sql); $rs=$stmt->fetch(PDO::FETCH_ASSOC); echo("Test for {$value} returns id {$rs['id']} and data {$rs['data']}<br>"); } date_default_timezone_set(

Inserted record and tried to get last insert id after that getting this error "Fatal error: Call to undefined method PDOStatement::lastInsertId()".

问题 I'm trying to update data in a table with a BIT type value in it, like the following : // $show_contact is either '1' or '0' $query->bindValue(':scontact', $show_contact, PDO::PARAM_INT); The problem is, it never changes the value, it remains '1' as set on PHPMyAdmin.
